Plant growth stimulator

Abstract

A plant growth stimulator useful for promoting and maintaining plant growth, wherein said stimulator is post-microbial culture inoculation nutrient medium consisting of black tea and a carbohydrate source, wherein the culture is consisting of Acetobacter xylinum, Candida sp . and Zygosaccharomyces rouxii , and a process for the preparation of the plant growth stimulator, and further, a method of promoting and maintaining the growth of plants using the plant stimulator having multiple disease resistance activity.

1. A method of promoting and maintaining growth of plants using a plant stimulator composition having multiple disease resistance activity, the stimulator composition comprising a post-microbial culture inoculation nutrient medium composed of black tea and a carbohydrate source, wherein the culture comprises  Acetobacter xylinum, Candida  sp. and  Zygosaccharomyces rouxii , said method comprising:
 diluting a stock solution of the stimulator composition with water; 
 spraying the diluted stimulator composition on the plants, and 
 obtaining plants of increased growth having multiple-disease resistance. 
 
     
     
       2. The method according to  claim 1 , wherein the nutrient medium comprises a carbohydrate source of concentration ranging between 0.5–10% w/v, and black tea powder of concentration ranging between 0.1 to 1.5% w/v in water. 
     
     
       3. The method according to  claim 1 , wherein the nutrient medium comprises a carbohydrate source of concentration of about 2.5% w/v, and black tea powder of concentration of about 0.5% w/v in water. 
     
     
       4. The method according to  claim 1 , wherein said stimulator composition promotes flower and fruit growth both qualitatively and quantitatively. 
     
     
       5. The method according to  claim 1 , wherein the dilution ranges between 0.2 to 5%. 
     
     
       6. The method according to  claim 1 , comprising spraying the stimulator composition on foliage. 
     
     
       7. The method according to  claim 1 , wherein the stimulator composition is sprayed about 1–5 times on the plants. 
     
     
       8. The method according to  claim 1 , wherein the stimulator composition shows activity after about two sprays. 
     
     
       9. The method according to  claim 1 , wherein a minimum of three sprays are required for desired changes. 
     
     
       10. The method according to  claim 1 , wherein the stimulator composition provides multiple disease resistance to plants. 
     
     
       11. The method according to  claim 1 , wherein the diluted material is a mixture of organic acids, and low molecular weight polyphenols. 
     
     
       12. The method according to  claim 1 , wherein the stimulator composition is sprayed on the plants at an interval of about 7–18 days. 
     
     
       13. The method according to  claim 1 , wherein the stimulator composition is stored and transported in dry form and used by diluting in water for about 25–35 minutes. 
     
     
       14. The method according to  claim 1 , wherein the stimulator composition is active for about 100 days. 
     
     
       15. The method according to  claim 1 , wherein spraying comprises spraying to achieve a doubling of plant stalk diameter. 
     
     
       16. The method according to  claim 1 , wherein the spraying comprises spraying to achieve a flower diameter increase of about 60–70%. 
     
     
       17. The method according to  claim 1 , wherein spraying comprises spraying to achieve a flower bud emergence as high as about 98%. 
     
     
       18. The method according to  claim 1 , wherein the spraying comprising spraying the leaves of the plant to obtain leaves having increased luster. 
     
     
       19. The method according to  claim 1 , wherein the spraying comprises spraying to achieve an increase in a number of flowers per plant increases of about 150–200%. 
     
     
       20. The method according to  claim 2 , wherein the spraying comprises spraying to obtain blooming of all flowers at one time.
